CVE-2025-25604 is a medium severity vulnerability found in the Totolink X5000R firmware version 9.1.0u.6369_B20230113. This vulnerability allows command injection via the vif_disable function located in mtkwifi.lua, leading to potential unauthorized command execution. The CVSS score of 6.5 indicates a notable risk to network security, requiring organizations to take this threat seriously.
The vulnerability can be exploited over the network (attack vector: NETWORK), and it has low complexity (attack complexity: LOW) with no privileges required for exploitation. This means that an attacker does not need prior access to the system to execute malicious commands, making it particularly dangerous.
Organizations utilizing the affected Totolink X5000R firmware should prioritize remediation efforts. The urgency is underscored by the ease of exploitation and the potential impacts on confidentiality and integrity, both of which are rated as low. If left unaddressed, this vulnerability could lead to unauthorized access and manipulation of the device.
Currently, there are no known exploits in the wild, but the possibility remains for future attacks. Therefore, proactive measures are essential. Organizations should review their firmware versions and apply any necessary patches to mitigate this vulnerability.
Vulnerability Details
The official description of CVE-2025-25604 states that "Totolink X5000R V9.1.0u.6369_B20230113 is vulnerable to command injection via the vif_disable function in mtkwifi.lua." This vulnerability is classified under CWE-77 (Command Injection), indicating a serious security flaw in how the firmware processes input commands.
The vulnerability has a CVSS score of 6.5, which categorizes it as medium severity. This score reflects a network attack vector with low complexity, no privileges required, and no user interaction needed. The impacts on confidentiality and integrity are rated as low, while availability is unaffected.
The affected product is the Totolink X5000R firmware, specifically version 9.1.0u.6369_B20230113, released on February 21, 2025. Organizations should ensure they are not using this vulnerable version.
Technical Analysis
The root cause of the vulnerability lies in the insecure handling of commands in the vif_disable function within mtkwifi.lua. This flaw allows an attacker to inject arbitrary commands that the firmware may execute, leading to potentially devastating consequences.
The attack vector for this vulnerability is network-based, meaning an attacker could exploit it remotely without needing physical access to the device. The complexity of the attack is low, as it does not require any special conditions or privileges to initiate.
No user interaction is required for this vulnerability to be exploited, making it particularly dangerous. The potential impacts include low confidentiality and integrity, meaning sensitive data could be disclosed or altered without authorization.
Risk & Impact Analysis
The real-world risk posed by CVE-2025-25604 is significant. Given the ease of exploitation and the potential for command injection, organizations using the affected firmware could face unauthorized access to their devices. This vulnerability could allow attackers to manipulate the device's functionality, leading to possible data breaches or service disruptions.
Organizations should assess their deployment risk associated with this vulnerability. The impact could vary widely depending on the device's role in the network, but even low-impact scenarios can lead to greater security issues if left unchecked.
The urgency for addressing this vulnerability is high, as the ease of exploitation could lead to an increased risk of attacks. Organizations should prioritize patching this vulnerability to minimize their exposure to potential threats.
